磷矿粉的有效利用途径综述

Advance in Effective Utilization of Phosphate Rock (PR)

磷是植物生长发育所需的营养元素之一,其主要来源于土壤。我国磷矿资源丰富但大多为中低品位磷矿,近年来磷矿粉直接施用效果的研究成为国内外共同关注的热点。本文从磷矿资源优化、高效利用的角度,从土壤性质、磷矿粉自身性质以及植物种类三方面分析了影响磷矿粉肥效的主要因素,综述了提高磷矿粉肥效的活化技术,探讨磷矿粉的合理施用,为合理利用中低品位磷矿粉、提高磷肥的利用率、降低磷肥的生产成本提供理论依据。对缓和目前磷肥严重短缺、氮磷钾协调等方面会有所帮助。

This paper analyzed the main factors affecting the phosphate rock fertilizer （PR）, reviewed technologies to improve the activation of the phosphate rock fertilizer, and discussed the rational application of phosphate rock （PR）. Then the paper provided a theoretical basis for the rational utilization of low-grade phosphate rock so as to improve its utilization efficiency and to reduce its production costs. The paper was hoped to ease the currently serious shortage of fertilizers, and improve the NPK coordination, etc.
